7.6 What to do in case of emergency
The emergency procedure described here must be applied immedi-
ately in the interest of the safety of the staff, in order to secure an area
in which an unshielded radiation source exists or is assumed to exist.
An emergency situation exists if a radioactive source is no longer
inside the source holder, if the source holder cannot be switched to "
OFF " position or if an increased local dose rate has been detected in
the proximity of the source holder.
The emergency procedure protects the affected persons until the
responsible radiation safety officer arrives and prescribes further
measures.
The person charged with the supervision of the radiation source (i.e.
the person stipulated and authorized by the plant operator) is respon-
sible for implementing this procedure.
